    @blablubbabc: Go

    I got the same error its a outdated version of powernbt so you need to downgrade bukkit or spigot.

    What is your version of bukkit and plugin?

    Seems to be broken: _ExceptionInInitializerError: null' whenever I run the first item related command.

    Can you add the ability to use scripts from paste bin?

    i;e /nbt pastebin 7RS20evc

    It would then run this pastebin script http://pastebin.com/7RS20evc

    Or make it so you can save the scripts too the server box and name them, so something like this would also work

    /nbt script scriptName.txt

    @Adam_Nox: Go

    No. PowerNBT has only "hex" formatting filter.

    I can suggest you to use the VarScript plugin + Groovy + NBTTools module
    but it is very difficult for the average user
    /g>> ( nbt(me).Attributes[1].Base*100 as int ) + "%"
    [VarScript] 40%

    Is there any way to format, or apply multiplication to values retrieved in queries, for display purposes only?

    One specific example, let's say I want to tell a player they have 40% knockback resist. The value that comes back when issuing the query is double base: 0.4. Is there a way to convert that to return just 40%, or as part of chat command response customize at all?
